2005 GMC Savana Van Owner's Manual - Page 72

Airbags may inflate at different crash speeds. For example: • If the vehicle hits a stationary object, the airbag could inflate at a different crash speed than if the object were moving. In any particular crash, no one can say whether an airbag should have inflated simply because of the damage to a vehicle or because of what the repair costs were. Inflation is determined by the angle of the impact and how quickly the vehicle slows down in front or near-frontal impacts. If the GVWR (Gross Vehicle Weight Rating) of your vehicle is 8,500 lb (3 855 kg) or above, your vehicle has single stage airbags. If the GVWR is below 8,500 lb (3 855 kg) then your vehicle has dual stage airbags. You can find the GVWR on the certification label on the rear edge of the driver's door. See Loading Your Vehicle on page 4-31 for more information. • If the object deforms, the airbag could inflate at a different crash speed than if the object does not deform. • If the vehicle hits a narrow object (like a pole) the airbag could inflate at a different crash speed than if the vehicle hits a wide object (like a wall). • If the vehicle goes into an object at an angle the airbag could inflate at a different crash speed than if the vehicle goes straight into the object. The frontal airbags (driver and right front passenger) are not intended to inflate during vehicle rollovers, rear impacts, or in many side impacts because inflation would not likely help the occupants. Single Stage Airbags If your vehicle has frontal airbags with single stage deployment and your vehicle goes straight into a wall that does not move or deform, the threshold level is about 9 to 16 mph (14 to 26 km/h). (The threshold level can vary, however, with specific vehicle design, so that it can be somewhat above or below this range.) 1-66
